To all whom thirty concern.:

Be it known that I, ENOOH .VOOD, of Pittsburg', in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Puddling and Ballin g Furnaces 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompan yin g drawings, which form part of this specification, in which- Figure l is a vertical section of furnace. Fig. 2 is a plan view. Fig. 3 is a perspective view of the balling-tool.

My invention relates to that class of puddling and ballin g furnaces wherein the metal bed or basin is made to revolve, and, by the use of a stationary balling-tool the metal, when properly worked up, is balled all at once by one single operation; and my invention oo nsists, first, in the novel construction ofthe ballin g-tool 5 and, secondly, in the novel means for excluding air from the rotary basin, all as hereinafter specifically described and claimed.

For these purposes I construct a puddling and balling furnace as follows: I change the shape of the usual reverberatory furnace by narrowing its bore at or about the circular metal basin, forming a shoulder or offset in the furnace, whose projection culminates at about the center ofthe metal basin. This, by directing the heat into the basin and upon the metal, hastens and facilitates the operation of puddling. To the lipped or iianged edge of the circular metal basin I attach a deep cylindrical ilange, extending from the lip ou the basin down to the foundation-plate, and into an annular groove in the same, which is kept filled with sand orwaterbyhoppers or pipes adapted for the purpose. This cylindrical flange, which is vertical, is provided near the bottom with downwardly-curved annular flanges inside and outside, and, respectively, overlapping vertical flanges rising from the two sides of the annular groove in the fbundation-plate. The purpose of these flanges is to exclude slag, cinders, or any foreign substance from entering the groove, and thereby clogging the same. The cylindrical ange being fastened air-tight at drawings, A represent a reverberatory furnace containing the rotating basin B. At C are shown the shoulders or offsets in the side walls of the furnace. b b designate the lip or flange on the basin B. D is the cylindrical vertical iiange, extending down into the foundationplate E, and having near its bottom downwardly-curved annular flanges e e', overlappmg the vertical flanges e e lining the trough e4 in the foundation-plate. The central vertical shaft F is attached to the metal basin B,

also supported by a ring, f, braced by rods ff, which are constructed with a shoulder to permit them to enter only a proper distance into the foundation-plate E. H is the rod or handle of the hailing-tool, furnished with furcated pintles Z Z', upon which hinge the wings h in pairs. This tool passes through the slide in the door, and is removed in the same manner.

Having thus fully described my invention- I claiml its top to the lip of the metal basin, and revolving with it, and the sand in the groove preventing access of air, the metal in process of puddlin g is absolutely secure against danger arising from the admission of atmospheric air or vapors, which might injure the quality of the metal, while the air has free ingress to the exterior surface of the metal basin for cooling purposes. The cylindrical flange serves, also7 as a partial support for the metal basin. The latter is otherwise supported on a central vertical shaft, held in place by a ring supportinto the foundation-plate. This shaft rests in a step or socket below the foundation-plate, and is xed to, and revolves with, a beveled wheel which meshes with a pinion-wheel xed to a horizontal shaft, the whole so arranged that, by turning the latter, the vertical shaft revolves, and thus rotates the furnace-bed or metal basin.

In the ordinary sliding door I construct another slide for the admission of the vballingtool. The metal is puddled by the stationary Hail-shaped rabble, and, when ready for balling, this is withdrawn, and the balling-tool inserted through the slide. This tool consists of a rod bent at right angles twice, thus continuing in parallel lines. The interior end of the rod is enlarged into a heavy plate or win g, so constructed that when lowered into the basin it will extend from the circumference to the center of the same. To the end of this are attached one, two, or more pintles, upon which similar wings. in pairs, rigidly xed, are loosely hung in such a manner relatively that, when spread out in the basin, they form radiuses, and divide the basin into three, tive, or .more equal segments, and are also so hung that when the tool is lifted from the basin the wings or enlargements fall together in a compact form, easily removable through the doorslide. Vhen the metal is puddled this tool is inserted and lowered into the mass of molten metal, cuts it into three, five, or more equal portions, each of which then, by the rotation of the basin, is kept rolling and tumbling about until rmly balled, when they are ready for the squeezers or rolls.

Reference being had to the accompanying 1. The ballingtool, consisting of the handle H, with the diverging wings 7L pivoted or hin ged thereon, substantially as described and shown.

2. The combination, with the cylinder D and the furnace-wall surrounding the same, ofthe intervening annular sand-joint, substantially as described. Y

3. The cylinder D, in combination with the rotary basin B and the water-trough e4,l said trough being formed in the base of thefurnac'e, substantially as shown and described.

4. The guard-nan ges ee', in combination with the cylinder D and trough e4, substantially as and for the purposes specified.

In testimony that I claim the foregoing, I. have hereunto set my November, 1874..
